Multi-Wavelength Studies of Spectacular Ram Pressure Stripping of a Galaxy. II. Star Formation in the Tail
Masafumi Yagi, Liyi Gu, Yutaka Fujita +5
With multiband photometric data in public archives, we detected four intracluster star-forming regions in the Virgo cluster. Two of them were at a projected distance of 35 kpc away…
Discovery of nine extended ionized gas clouds in a z=0.4 cluster
Masafumi Yagi, Liyi Gu, Yusei Koyama +4
From deep H-alpha imaging data of Suprime-Cam/Subaru, we discovered nine extended ionized gas clouds (EIG) around galaxies in Abell 851 cluster (A851) at z=0.4. We surveyed 30 x 25…
A Keck/LRIS Spatially-Resolved Spectroscopic Study of a LINER Galaxy SDSS J091628.05+420818.7
Hyun-Jin Bae, Jong-Hak Woo, Masafumi Yagi +2
Using spatially-resolved spectra obtained with the Low Resolution Imaging Spectrometer at the Keck I telescope, we investigate the nature of ionizing sources and kinematic properti…
The Universal Initial Mass Function In The XUV Disk of M83
Jin Koda, Masafumi Yagi, Samuel Boissier +5
We report deep Subaru Halpha observations of the XUV disk of M83. These new observations enable the first complete census of very young stellar clusters over the entire XUV disk. C…
Kinematics and excitation of the ram pressure stripped ionized gas filaments in the Coma cluster of galaxies
Michitoshi Yoshida, Masafumi Yagi, Yutaka Komiyama +4
We present the results of deep imaging and spectroscopic observations of very extended ionized gas (EIG) around four member galaxies of the Coma cluster of galaxies: RB199, IC4040,…
A dozen new galaxies caught in the act: Gas stripping and extended emission line regions in the Coma cluster
Masafumi Yagi, Michitoshi Yoshida, Yutaka Komiyama +8
We present images of extended H-alpha clouds associated with 14 member galaxies in the Coma cluster obtained from deep narrow band imaging observations with Suprime-Cam at the Suba…
